Cardiovascular Fitness Improves Cardiac Interoceptive Accuracy
The FASEB Journal, 2022Background . Many of the sensory receptors encoding touch, temperature, pain, and visual or auditory cues are known; these exteroceptive receptors allow us to respond to external threats. The

Cardiac interoception is enhanced in blind individuals
2022AbstractBlind individuals have superior abilities to perform perceptual tasks that rely on exteroceptive information, since visual deprivation is associated with massive cross-modal plasticity. However, it is unknown whether neuroplasticity after visual loss also affects interoception, i.e., the sensations arising from one’s inner organs that convey ...

Response inhibition is disrupted by interoceptive processing at cardiac systole
Biological Psychology, 2022The present study investigated how cardiac signals influence response inhibition at both behavioral and electrophysiological levels by using participants' electrocardiogram signals to control the occurrence of events in a stop-signal task, in which the go cue was unpredictably followed by a stop signal requiring the cancellation of the prepotent ...

Panic attacks and interoceptive acuity for cardiac sensations
Behaviour Research and Therapy, 1993It has been suggested that perception of visceral changes, and cognitive reactions to such changes, may be important for triggering panic attacks. It remains to be determined, however, whether people with panic attacks are actually characterized by enhanced perceptual acuity for interoceptive stimuli.

Measuring Interoception: the CARdiac Elevation Detection Task (Preprint)
2021UNSTRUCTURED Interoception has increasingly been the focus of psychiatric research, due to its hypothesised role in mental health. Existing interoceptive tasks are often burdensome and require specialised equipment, limiting their usage in vulnerable populations.

Attention interference for emotional stimuli in cardiac interoceptive awareness
Psychophysiology, 2014AbstractPrevious research has shown that individuals with good perception of cardiac signals, referred to as cardiac interoceptive awareness, experience emotions more intensely. To investigate if emotional experience in high cardiac interoceptive awareness arises from biases in attention, we compared the performance of participants with high versus ...

Cardiac Contractility Drives Cardiac Interoception
PhysiologyIntroduction: Many of the receptors for the exteroceptive senses (e.g. vision, hearing, smell, touch, pain, etc.) are known. Interoception allows us to sense threats to our “milieu interior.” The mechanisms by which threats induce a feeling of anxiety manifested by heart palpitations, shortness of breath (dyspnea), and gastric awareness (queasiness ...

Interoceptive discrimination in intact humans: Detection of cardiac activity
Physiology & Behavior, 1974Abstract Individuals may be trained to discriminate between vibratory stimuli that are contingent on their heart beats and vibratory stimuli that display the same temporal and physical properties as the contingent stimuli, but that are independent of their heart beats.

Biological Psychiatry: Cognitive Neuroscience and Neuroimaging
AbstractBackgroundInteroception represents perception of the internal bodily state which is closely associated with social/emotional processing and physical health in humans. Understanding the mechanism underlying interoceptive processing, particularly its modulation, is thus of great importance.

Interoceptive cardiac expectations to emotional stimuli predict visual perception.
Emotion, 2020Previous work exploring the interplay between the processing of internal bodily signals and the perception of external events suggests a correlative relationship between both domains. Here, we demonstrate an experimentally induced link between visual perception and the emotional modulation of interoceptive cardiac signals. We pair an emotion repetition-
